Open-book tests in a university course

In the few available studies on the use of books in examinations, open-book tests have been found to reduce pre-test memorization and anxiety during examinations without affecting academic performance. However, these studies were made with students in non-book systems, whereas systems which allowed books in all exams might be thought likely to create a non-fact-learning attitude in students. The present study was undertaken in a book-allowing system with 120 students during a regular course in physiology at a medical school. Each group sat two parallel 60-item multiple choice tests and used books in one test but not in the other. The tests took place about four weeks prior to the final examination, which is of the same type as the experimental tests. Recall items could yield less than 15% of maximum points, so that interpretation and problem-solving items predominated. Total test points with and without books did not differ significantly. An analysis of variance showed that the effect of books on recall items was only slight and that the two tests varied in difficulty, in spite of efforts to secure equality.     

Integrating Facebook in Upper Secondary Biology Instruction: A Case Study of Students’ Situational Interest and Participation in Learning Communication

The sciences are often perceived by students as irrelevant as they do not see the content of science as related to their daily lives. Web 2.0-mediated activities are characterized by user-driven content production, collaboration, and multi-way communication. It has been proposed that employing Web 2.0 in educational activities will promote richer opportunities for making learning personally meaningful, collaborative, and socially relevant. Since Facebook is already in use among youths, it potentially provides a communicative link between educational content and students’ lives. The present study was conducted as a case study to provide an inductive, explorative investigation of whether and how the integration of Facebook into upper secondary biology can affect interest in biology and participation in learning communication. The results indicate that the coupling of formal and informal communication practices on Facebook serves to maintain interest and open up new learning possibilities while at the same time creating barriers to communication. These barriers are due to distractions, ethical issues, and a certain depreciation of the activities ensuing from the everydayness of Facebook as a communication platform. In conclusion, use of Facebook as an educational platform is not clearly good or bad.     

The Case for Dynamic Models of Learners' Ontologies in Physics

We cannot really understand how to create computer support for collaborative learning without first becoming clearer about what we mean by communication, collaboration, and learning. After distinguishing several conceptions of communication, and highlighting transformative communications for learning, I consider how, via broadband telepresence, distributed multimedia learning environments may establish such communications by adequately acknowledging the social and material embeddedness of everyday communication. I then describe high-priority areas for advancing this agenda: in sociocultural theory, in examining conceptual change by means of conversational analysis, and in technically establishing affordances of tools to sustain and potentially enhance joint activity beyond the here-and-now and the face-to-face.     

Sympathoadrenal and parasympathetic responses to exercise

Exhaustive exercise is associated with a persistent sensation of weakness and sometimes nausea suggesting abdominal vagal activity. We measured plasma indices of sympathoadrenal (adrenaline, noradrenaline, dopamine) and vagal (pancreatic polypeptide) activity before, during and after submaximal and maximal exercise in healthy young subjects. Plasma adrenaline, noradrenaline and dopamine increased to 8.5 (range 7.4–40.5), 48.0 (32.3–100.5) and 1.8 (1.2–6.6) nmol l^–1 respectively (n = 5), during maximal exercise and decreased towards control values within 15 min of rest. Pancreatic polypeptide (n = 10) increased only during maximal exercise and reached its highest value, 48 (21–145) pmol l^–1, after exertion. The results conform to an increase in sympathetic activity during exercise and a persistent vagal activity after intense exercise which could contribute to the sensation of weakness.     

Distractor Similarity and Item-Stem Structure: Effects on Item Difficulty

Methods for detecting copying of multiple-choice test responses developed over a 60-year period are reviewed and compared with respect to their effectiveness and the practicality of their application for groups of varying size. Although effective detection methods are routinely used in large admissions and licensing testing programs, they are seldom applied in the areas of standardized testing or classroom testing in schools or colleges. Circumstances associated with this discrepancy are discussed.

This engaging book reviews current policy and practice in the development and use of open educational resources (oer ) internationally. It includes chapters that examine the current environment for oer development and use, including government and institutional policy, as well as a range of case studies that describe the development, re‐use and implementation of oer with a particular emphasis on developing countries. The book is useful for educators, educational leaders, learning resource developers, and government policymakers. Sara Hammer

This book examines strategic curriculum change through a study of change activities within a group of international research‐based universities. It echoes a range of concepts, processes and tools relevant to curriculum change by way of real world (even if occasionally rarefied) case studies from each of these institutions. The target readers include university leaders at all levels and academic curriculum developers. Sara Hammer
